Search for: [Abstract = "Eye movement abnormalities are common sign of many neurodegenerative disease like Parkinson`s disease \(PD\), spino\-cerebellar ataxia \(SCA\) or Huntington disease \(HD\). Even though essential tremor \(ET\) is the most prevalent movement disorders, the spectrum of eye movement abnormalities for this disease has not been entirely explored yet. There are only two papers published as yet concerning eye movement abnormalities in ET which were performed on small groups of patients \(17 and 12\). The presence of accompanying cerebellar or parkinsonian signs in ET patients may result in in misdiagnosis ET as SCA or PD. Oculographic examination is a sensitive biomarker enable to detect subtle changes in the nervous system, so it can be helpful for differential diagnosis of diseases with similar clinical manifestation or classification of neurodegenerative diseases. Aim of the study was to evaluate eye movement abnormalities in ET patients in comparison with matched according to age and gender controls and patients with other neurodegenerative disease like PD, SCA and HD and to assess the relations between eye movement abnormalities and other signs and course of ET. 50 ET patients and matched according to age and gender 50 PD, 42 SCA, 50 HD and 42 healthy controls were includes to the study. The severity of ET signs was assessed by STSS and CRST, PD – UPDRS, H \& Y and S \& E, SCA –ICARS and SARA,"]
